4.1.6 Over Temperature Switch

The Danfoss harmonic filters AHF 005 and AHF 010 are equipped with a galvanic isolated thermal switch (not PELV), that is closed under normal
operating conditions and open if the filter is overheated.
When connecting the A/B terminals directly to terminal 12 and 27 of the drive, Protective Extra Low Voltage (PELV) can no longer
be guaranteed!
NB!
A controlled ramp down within 30 s is allowed without causing overheat damage to the filter.

Design Guide
.
Example: Connect terminal A of the harmonic filter to terminal 12 or13
(voltage supply digital input, 24V) of the Danfoss frequency converter and
terminal B to terminal 27 (digital input "Coast Inverse") the frequency
converter will let go of the motor (coasting) and thereby unload the filter
if an over temperature is detected.
